KALEIDOSCOPE.

To all whom it may concern;

Be it known that I, ANTON STABLA, a subject of the King of Hungary, anda resident of Eccles, in the county of Raleigh, State of West Virginia,have invented certain new and useful Improvements in Kaleidoscopes, ofwhich the following is a specification.

This invention relates to improvements in ka-leidoscopic tubes and hasits special object the provision of an exceedingly simple andinexpensive tube, formed from a single piece of material.

A further object is to provide a kaleidos scopic tube which may be soldat an unusually low price and which is capable of performing all thefunctions of an expensive instrument.

These and other like objects are attained by the novel construction andcombination of parts hereinafter described and shown in the accompanyindrawings, forming a material part of tliis disclosure, and in which': a

Figure 1 is a longitudinal sectional view taken substantially throughthe center of a tube made in accordance with the invention.

Fig. 2 is a transverse sectional view takenon line 22 of Fig. 1, and rFig. 3 is a transverse sectional view taken on line 33 of Fig. 1.

The invention comprises an inner triangular tube having its wallsrespectively 1O, 11 and 12, formed from a single sheet of highlypolished material having a mirrorlike reflectin surface, the elements 10and 12, being sol ered together at the joint 14.

The surrounding circular tube 15, is formed by bending the edge of theelement 12, outward into a cylinder, the opposite edge 16 being likewiseheld by a soldered joint, the triangular tube making contact at itsapices with the interior of the cylindrical tube at their points ofintersection, and being soldered thereto if desired.

A cap 18, is secured over one end of the cylindrical tube 15, by meansof the annular flange 19, and provided with an aperture 20,

through which a view may be taken. A

similar cap 22 is provided at the opposite.

end of the tube held in position by the annular flange 23, and containsarelatively large circular opening 24.

The adjacent end of the triangular tube, comprised of the members 1O, 11and 12 are shortened as shown in Fig. 1, while the outer, cylindricaltube 15 extends therebeyond and'has fixed in it, two transparent plates,respectively 25 and 26, made of glass or like material, and having inthe space between them a plurality of colored fragments 28, of brokenglass or the like which, as the tube is rotated, revolves into variousformations. A spacer 29 is interposed between the transparent plates soas to hold them substantially parallel and the outer plate is held inposition by the cap 22.

The operation of the tube is in all respects similar to those which arewell known in the art, the invention residing in the structural materialemployed and in its peculiar conformation.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is:

In a kaleidoscopic tube the combination of a unitary structureconsisting of an inner triangular tube, a mirror-like reflecting surfacein said tube, having its edges joined by solder and an outer cylindricaltube circumjacent to said triangular tube, the edges of said tubes beingjoined by solder, said outer tube being of greater length than saidinner triangular tube, apertured caps at the ends of said cylindricaltube, a air of transparent plates set in one end 0 said cylindricaltube, a spacer between said plates one of which contacts with the end ofsaid triangular tube, said tubes being made of a highly polishedmirror-like material, and a plurality of colored fragments disposedbetween said transparent plates.

In testimony whereof, I have aifixed my signature.

ANTON STABLA.
